First check recorded on November 2, 2026. This record follows the releases of go-flare, the software Flare and Songbird validators run, kept by Flare Foundation at https://github[.]com/flare-foundation/go-flare[.] Changes before this day are in that history. This record starts with the changes from the last 30 days.
Flare Foundation published go-flare v1.15.1-rc.1 on October 29, 2026. It is marked as a pre-release. Their notes say: This is a pre-release for the Coston2 network only. It updates the Flare and Songbird codebase to AvalancheGo v1.15.1 (Helicon upgrade). The node refuses to start on the Flare and Songbird networks (mainnet is not supported); the activation times for the Coston, Songbird and Flare networks will be scheduled in the final release.
Flare Foundation published go-flare v1.14.2 on October 23, 2026. Their notes say: This release updates the Flare and Songbird codebase to AvalancheGo v1.14.2. The upgrade is optional but encouraged. It is backwards compatible with v1.14.0 and does not schedule any new fork times. Note: Coreth and Subnet-EVM are now grafted into the AvalancheGo tree - there is no separate coreth module anymore.
